Description of a series of cases in which otogenic encephaloceles in patients requiring canal wall down (CWD) mastoidectomies were repaired via a transmastoid approach.
Case series.
Tertiary-care hospital.
Eleven cases of otogenic encephaloceles in patients requiring CWD mastoidectomy for chronic ear disease.
Surgical repair of an otogenic encephalocele using a transmastoid approach.
Success of repair, number and size of defects, materials used for repair, complications encountered in surgery, pure tone average air-bone gap (PTA-ABG).
Eleven cases were identified. Two of these patients had a prior CWD cavity while the remainder received CWD mastoidectomy simultaneously with encephalocele repair. None of the patients required revision of encephalocele repair. Mean preoperative PTA-ABG was 30 dB and mean postoperative PTA-ABG was 28 dB (p = 0.66).
A single-stage strictly transmastoid approach to otogenic encephalocele repair may be effective in patients with prior CWD mastoid cavities or requiring concurrent CWD mastoidectomy for chronic ear disease and/or cholesteatoma.
描述一系列通过经乳突入路修复需要行开放式乳突根治术（CWD）的患者耳源性脑膨出的病例。
病例系列。
三级医疗医院。
11例因慢性耳部疾病需要行CWD乳突根治术的耳源性脑膨出患者。
采用经乳突入路对耳源性脑膨出进行手术修复。
修复成功率、缺损数量和大小、修复所用材料、手术中遇到的并发症、纯音平均气骨导差（PTA - ABG）。
共确定11例患者。其中2例患者曾有CWD腔，其余患者在修复脑膨出的同时接受了CWD乳突根治术。所有患者均无需对脑膨出修复进行翻修。术前平均PTA - ABG为30dB，术后平均PTA - ABG为28dB（p = 0.66）。
对于既往有CWD乳突腔或因慢性耳部疾病和/或胆脂瘤需要同时行CWD乳突根治术的患者，采用单阶段严格经乳突入路修复耳源性脑膨出可能有效。
